Can I produce a seamless pattern from a 45 degree rotated design?

Hi guys, I’m having a big problem with wanting to produce the design with a 45 degree rotation to the elements as it looks much better as a finished pattern. However i don’t know if this is possible, the only way i can make this repeated pattern after downloading the tile is in an app which allows me to zoom out of a repeated pattern and change the angle to create something like a 5 then 4 then 5 repeated elements as 45 degrees (if that makes sense). But i really want to export something that i can possibly sell with the elements repeated in the pattern this way. Is there a way to do that? As far as i can see the rotation is only available in surface View but i can’t export that as a seamless pattern. Would really appreciate some helpful advice. Thanks!
